Lithuanian and Latvian are the only remaining Baltic languages. Both languages have many things in common. Lithuanian, however, adopted fewer words and phrases from German and other languages. However, long ago Lithuanian was affected by the Slavic languages, so the main barbarisms were replaced with Lithuanian words only in 1920, by Lithuanian philologist Jonas Jablonskis and others.

There are two main dialects of Lithuanian. Samogitian is the dialect mostly used in West Lithuania, the other, widely used in the whole country is Aukštaitian (High-landers' dialect). The standard Lithuanian comes from West-Aukštaitian.
